PATENTLEATHERREIPAIRING MACHINE.

Application filed December 2, 1916, Serial No. 134,701. Renewed. March5, 1925.

To all whom it may concern? Be it known that I, FREDERICK M. Fun- BER, acitizen of the United States, residing at Revere, in the county ofSuffolk and State of Massachusetts, have invented certain Improvementsin Patent-Leather-Repairing Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings inclicatinglike parts in the several figures.

This invention relates to machines for use in the manufacture of bootsand shoes. More specifically it relates to improvements in a machine forrepairing imperfections in the tips of boots or shoes made of patentleather.

In my Patent No. 1,096,423, I have described a machine which isespecially adapted for repairing cracks or other imperfections which maybe caused during the manufacture of a patent leather shoe. This machineis provided with atool having a relatively broad resilient work surfacearound which is wrapped a strip of sheet material. Difficulty issometimes experienced in bringing this tool closely into the rand creaseof a shoe and, in order to overcome this difficulty, I have devised anovel machine in which there is provided an auxiliary tool preferablyhaving a relatively narrow work surface and arranged so that it may bebrought into or removed from operative position beside and immediatelyadjacent to said main tool so that it occupies substantially the sameposition with relation to the whole machine as the main tool and istherefore conveniently located for the application of work to the toolby the operator, and this constitutes one important feature of theinvention.

In the illustrated embodiment, the main tool is given a compoundmovement, as one of oscillation and reciprocation, while the auxiliarytool receives but one component of this movement, as the oscillation.Important features ofthe invention reside in the arrangement of twotools which are connected to a common shaft so that one tool hasimparted to it one sort of movement while to the other tool there isimparted a different sort of movementwhich is only a part of themovement of, the first tool. Such a machine is described in thefollowing specification and shown in the accompanying drawings 1nWl11Cll Fig. 1 is an end View of amachine to The detailedconstruction'of a machine of this type may be seen from an inspection ofthe above-mentioned patent. It will be understood that such a machinecomprises a standard or frame on which is rotatably supported a maintool 12 which is mounted upon a tool shaft 14 and that a combinedoscillating and reciprocating mo tion is imparted to this shaft from apower shaft 8 rotated by means of a driving pulley 16.

Below the shaft 8 and extending at right angles thereto is supported thetool shaft 14, this shaftjbeing received inbearings formed respectivelyin. the casing and its cover. Mechanism is provided to transmit motionfrom the drive shaft to the tool shaft, to

reciprocate the tool shaft axially, to oscillate it about its axis andto give it a rotative movement when desired. The axial reciprocationofthe tool shaft 14 is effected by means of a collar 9 fast on the shaft14 and a lever 11 fulcrumed on a shaft 7 supported in bearings formed inthe casing. The lever carries at its lower end a roll positioned betweenthe flanges of the collar 9; and it is rocked on its fulcrum by means ofan eccentrio bushing 18 faston the drive shaft 8 and a short connectingrod 15 mounted on the eccentric and pivoted to the lever. be evidentthat when the shaft 8 and eccentric 18 are rotated, the connectionsdescribed will produce an oscillating motion of the lever 11 which willbe transmitted through the collar 9 to theshaft'lt, causing the shaft toreciprocate rapidly through its bearings. Boththe oscillating and rotarymovements of the shaft 14 are transmitted. thereto through a gear 17.This gear, 4 i

It will shown in Fig 4, has a slidingconnection with the hub of thecollar 9sthat permits the hub and the shaft 14 to slide axially of thegear, but compels the shaft to rotate witlrthe gear. A. spring21,interposedbetween the collar 9:1and gear 17, serves to hold the gearagainst the hearing in the casing as the shaft moves back and fprth.

Serial-N0. 750,303, filed Feb. 24:, 1913.

The tool.1 2- preferably comprises a rigid;

foundationor hub20 whichi's surrounded;

which. has: a forked end, provided with a cylindrical cross piece 34.Trapped around the body. of the. tool 12. andthe cross piece o fthe.plrmgerBO is a strip, of sheetmaterial 3.6..for thewell,understood.purpose of providing an easily; renewable surface forthe tool. Pins. 38 and, 410s are provided in the bracket for retainingeaphwf the plungers in position: with its spring compressedwhereby.thesstrip of sheet material may be readily removed and replacedthereon. At an intermediate point of the main bracket 26 is anauxiliarybracket l2 whichis pivotally. mounted upona springpresscd axle414k and held thereon by means of a nut 46 threaded to, said axle,Theboss 4E8 surounding aidi lo upon .the a n bracke outer end to formpin 56' for a. purpose to,belateiflexplained. Journaled the outing theauxiliary tool 60 comprising a thin disc of resilient material such asrubber backed up by a metal a plate 62.. On the other end of this shaftis a plate 64 provided with apertures adapted to beoperatively engagedwith the pins 24 secured to the work shaft 14. By means of this a1-rangement, the auxiliary tool will oscillate with the main tool but itsmotion will be in a fixed plane and it will have no motionlongitudinally of its axis as does the-main tool. Surrounding theauxiliary tool is a strip of sheet material 66 which is tensioned bymeans of the bar 34 in the corresponding spring-pressed plunger 32. a

As described in my previous patent, the

machine is so arranged that a feeding move ment, may be given to thestrip'ofsheet material, at will, so as to bring a fresh portion intoposition for use. This feeding movement is under control of the operatorwho will depress a latch 19 and at once release the sameto allow asinglerotation 'of the shaft with which the latch is associated.

This will'result in movingthe s'trip'of sheet material forward forapproximately an inch.

It will now be seen that if thecracksin the tip ofashoe run "into therand crease so far that they cannot be conveniently reached by means ofthejmain tool 12, then the auxiliary tool 60 maybe brought intooperative position beside the main tool and in substantially the sameposition relative to the frameas the main tool by pulling the bracket 42outward against the 'tensionof the spring 54, turning it through an arcof and releasing it jections 52 to engage'with thecorresponding verticalrecesses 50 and at the same time causing the apertures in the plate64'toengage, with the pins 24. Because of therelatively narrow-worksurface, whichfis here shown as tapered to a thin edge, this aux-iiliary tool with its coveringof cloth orsimilar, material may be broughtinto. the rand crease, in the manner illustrated in Fig. 2, much morereadily than could =thebroad faced tool 12. The thinness ofthe auxiliarytool necessitates the backing plate 62 in order that the tool may bekept in shape and not be distorted by use or by the tension of the stripof sheet material 66. "When the auxiliary tool is no longer required,the bracket may be returned to the vertical position, as-

shown in dotted lines in Fig. l, where it will not interfere with thefree use of the main tool 12. It shouldrbe noted that-whenfin thisposition, theextension 56 helpsto hold the loose strip 66 out of contactwiththe strip 36 associated with the main tool. In

view of the particular f'ormpand useiof the auxiliary tool, it isobviously undesirable to impart'to it any movement longitudinally of itsaxis. This result is readily secured by the peculiar connection betweenthe auxilso as to cause the:pr0-,

iary tool and the toolshaft 14. The auxiliary tool will, however, havean oscillatingmovement whereby the enamel will be thoroughly rubbed intothe work and may also be given a feeding movement similar to that of themain tool at the will of the operator.
